T5518: Add basic MLD support
Currently VyOS has `protocol igmp` option to enable IGMP querier and reports through FRR's pimd. I would like to add support for IPv6 as well since FRR's IPv6 multicast functionality has significantly improved. Enabling both MLD and IGMP on a VyOS router will allow us to turn on multicast snooping on layer-3 switches in dual-stack networks. Example commands: ``` // Enable on interface eth0 set protocols pim6 interface eth0 // Explicitly join multicast group ff18::1234 on interface eth1 set protocols pim6 interface eth1 mld join ff18::1234 // Explicitly join source-specific multicast group ff38::5678 with source address 2001:db8::1 on interface eth1 set protocols pim6 interface eth1 mld join ff38::5678 source 2001:db8::1 ```
